Abstract
A vibratory mechanism includes a motor, and a clutch having first and second output shafts. The first and second output shafts are connected with first and second eccentric weights. The clutch is operative to engage and disengage the inner and outer drive shafts from each other to change a phase difference between the first and second eccentric weights.
Claims15
A vibratory mechanism, comprising:
- a motor;
- a clutch having first and second output shafts, said clutch being connected to said motor;
- a first eccentric weight connected to the first output shaft of said clutch;
- a second eccentric weight connected to the second output shaft of said clutch;
- and
- wherein said clutch is operative to engage and disengage said first and second output shafts from each other to change a phase difference between said first and second eccentric weights.
A method for adjusting amplitude of a vibratory mechanism, the vibratory mechanism including first and second eccentric weights, a motor for driving the first and second eccentric weights, and a clutch connected to the motor and having first and second output shafts connected to the first and second eccentric weights, respectively, comprising:
- activating the clutch to change a phase difference between the first and second eccentric weights in order to change the vibration amplitude.
A method for adjusting amplitude of a vibratory mechanism as it makes a plurality of passes over a compactable material, the vibratory mechanism including first and second eccentric weights, a motor for driving the first and second eccentric weights, and a clutch connected to the motor and having first and second output shafts connected to the first and second eccentric weights, respectively, comprising:
- monitoring a speed and position of the output shafts via a computer controller;
- engaging or disengaging the clutch to cause the first and second eccentric weights to be 180° out of phase;
- and
- engaging or disengaging the clutch to increase the vibration amplitude to a desired level after a desired RPM is reached.
